AFAICT the HPC version is more expensive but you get extra tools for that
such as benchmarks, pre-compiled mpi, batch-scheduler from Platform.

But MPI is easy to intall and I would prefer other batch-schedulers instead
of the one of Platform so ... I wonder if the kernel/distribution itself is
more optimised ?

thanks for the tip.

No, we'll be using local file systems primarily and also a connection to a
SAN but no global filesystem.
